By great, I mean that I bow down to all the knowledgeable members here that can help

So after a bunch of digging around, I know that:
The OEM clutch master cylinder is AP8106713, Brembo part 10777011, Name PSC12. 12mm cylinder, piston length 37.5mm, spring length 37.5mm (probably)
I wanted to change it out to either a Brembo RCS, Nissin Radial/Axial or Frando Radial.
Now comes the hard part - which cylinder size.
From what I've read, the Brembo RCS 16 works. $$$
Nissin Radial 16 is the same, not too sure about the Axial sizing - maybe a 14? $$
Frando has a very decently priced radial that a lot of KTM and Aprilia guys are using - FMF-130S
Anyone here changed out their clutch MC to the above units with success?
